AttributeError: module 'signal' has no attribute 'SIGALRM'

[Demonweb]

I get the following error when running the Jupyter Notebook step.
This happens in PPO and Basic versions.
I have windows 10 and latest unity 2017.2.0b6 Personal

The Game opens up and the balls drop, but the tables do not move.
The brain is set to external.

I build the unity environment and put the .exe here : ....\ml-agents-master\python

ppo.py
setup.py
3DBall.exe
3DBall_data

here is what I updated in the Jupyter Notebook

General parameters

max_steps = 10000 # Set maximum number of steps to run environment.
run_path = "ppo" # The sub-directory name for model and summary statistics
load_model = False # Whether to load a saved model.
train_model = True # Whether to train the model.
summary_freq = 10000 # Frequency at which to save training statistics.
save_freq = 50000 # Frequency at which to save model.
env_name = "3DBall" # Name of the training environment file.
